. "A credo (pronounced [\u02C8k\u027Ee\u02D0do\u02D0], Latin for \"I Believe\") is a statement of religious belief, such as the Apostles' Creed. The term especially refers to the use of the Nicene-Constantinopolitan Creed (or less often, the Apostles' Creed) in the Mass, either as spoken text, or sung as Gregorian chant or other musical settings of the Mass."@en . . .
